Writing to Binary PCA, value not updating
I have a VM running SV5.1-3 with PLC Connect on a combined AS/CS and a Matrikon OPC simulator
On this system I have a restored a project backup to develop the additional OPC tags I will be adding to the project.
After testing the tags read/write on the VM I have exported/imported to the project reference system for testing with the OPC third party (metering system)
We have tested both the DI and AI signals from the OPC to the ICSS but when attempting to write out the Binary PCA value does not change.
I have installed a dummy DO with no connection on the signal configuration - the Binary PCA status properties all have Good quality
Using a Property Transfer I am writing to the value but it is not updating
(the PT is working as verified by adding a General property aspect in the same object and writing to a property with the same PT expression)

Did you forget to enable the Is Controllable checkbox?
Csn you post a write to the destination by any other means, eg an OPC test client?
